Rubik took almost a month to solve the cube himself, and it was licensed to Ideal Toy Corp in 1980. It is one of the largest selling toys of all time selling over 350,000 units, and was also popular among children in 1980.

There are nine colored squares on every face of the cube, where the squares can be moved to different positions on the 3D cube to return the puzzle to its original configuration. Solving the puzzle is quite hard until you get the knack of it.

There are players known as ‘Speedcubers,’ who compete with each other to solve the puzzle as fast as six seconds. Every Rubik Cube can be solved in 20 moves, and there are over 43 Quintilian permutations of the cube – that is, unique distributions of the 54 colored squares over the six faces.
